Substantially changed it, yes, in some ways; in one key way, not at all.
The Court of Appeal in my province (Saskatchewan) has implemented e-filing: all documents must be filed electronically, and then any party to the appeal has e-access to them. (Non-parties can get an account that allows browsing, I believe, but not filing.) When the Court gives its decision, the Registrar e-mails it to all parties. No paper copy to follow. The other courts don’t have that system, but I understand they’re looking at it.
Exchange of documents increasingly is done by pdf’s attached to e-mails. We have to agree with opposing counsel to use this approach, but as a matter of practice, it’s becoming the most common way to serve documents, other than initiating documents, like a Statement of Claim - those are still served in person.
Research has changed completely - I used to be a regular at the Court house library; now, the only time I go there is when I need some quiet time to work on a file, or they have a book I don’t have. But for statutes and case reporter series, it’s all on Westlaw/Carswell, or a competitor, Quicklaw, or a free service operated by the Law Societies, CANLII. I recently did a major brief working entirely in my own office. Now, I’m a bit of a dinosaur, and once I’ve found a lengthy case, I find that browsing it in a book is easier, but I don’t think my younger colleagues do that.
The e-versions are so prevalent that the Supreme Court of Canada has announced that it will stop printing the Supreme Court Reports - the official reports will be the e-versions.
Noting up a case (I think down south you call it “shepparding” or something) is tremendously improved, as all of the e-services have a “case cited” function; find a case you’re interested in, click on the “cited” button, and you get a list of how that case has been cited by other courts, whether it’s been overruled, and so on. Same for statutes; can use the search/cite functions to find out exactly when and where s. 43(1)(b) of an Act has been considered by the courts.
Oh, and I do almost all my own documents on my own computer now - I used to hand-write, and give them to my secretary, and she’d type a draft, and I’d proof-read the draft, and then give it back to her, and … you get the picture. Now, I do most of my own typing.
Remote access from home is an amazing thing. We’ve got a little guy, and I hate going into the office on weekends or evenings. Now, I don’t need to; for the most part, I can do whatever I need to do from my home computer, or by bringing my work laptop home for the secure access to files.
So, I’d say technology has completely changed the physical way I do my work.
However, the one key thing that hasn’t changed is the thinking piece. All of this technology helps me to find law quicker, to search it quicker, to share it quicker. The most important part, though, is thinking about it. And that’s not changed at all by technology.
